Hi everyone!Currently I'm dealing with a problem/error in fieldfox. At the end of each sweep, there is a error message on display saying that "ADC2 overload". I changed the output power to LOW but there is still this error message.. What should I do? I hope anyone can help me! Thanks in advance.

I am assuming you do not have an active device connected between ports 1 and 2.There could be a variety of reasons to see the ADC2 overload message. We'll have to just trouble-shoot it. I'm sending you a private message.

Hi Afsi! Thanx a lot for a quick reply and for you pm.Well, the antennas are connected to the ports, at first there was no problem.With the output power HIGH selected, this error message appeared sometime.So we set the output power to LOW and this error disappeared but after a while it started displaying again and again.I'll contact asap.Thanks again.

I see you posted this 9 months ago, but I have exactly the same issue with my FieldFox N9923A. Afsi thought it was a hardware issue, but was not sure. I also got errors about VCO's going unlocked on mine. When this occurs, the error message is flashed up for a very short duration

My problem seems to be intermittant and occurs with nothing on the test ports at all. Of course, this is a a condition which gives the maximum possible reflection for a passive device.
